SPECIFICATION forming part of Letters Patent No. 443,337', dated December 23, 1890.

Application tiled November 6, 1889. Serial No. 329,461. (No model.) l

To all whom it may concern:

Be it known that I, RICE D. SQPER, a citizen of the United States of America, residing at Marshall, in the county of Lyon and State of Minnesota, have invented cert-ain new and useful Improvements in Stoves, of which the following is a specification, reference being had therein tothe accompanying drawings.

This invention relates to certain improvements in cooking-stoves and hot-air heaters combined; and it consists in the novel construction and combination of parts hereinafter disclosed.

In t-he accompanying drawings, Figure l is a sectional elevation of my invention. Fig. 2 is a somewhat enlarged partly sectional and partly side View of a portion of said invention, parts also being broken-away. Fig. 3 is a horizontal section taken on the line y y of Fig. l. Fig. 4 is a similar section taken on the line z z of Fig. l. Fig. 5 is a like section taken on the line w w of Fig. l, and Fig. 6 is also a like section taken on the line a: oc of Fig. 1.

In the embodiment of my invention I enlploy a tire-box or combustion-chamber A, suitably secured upon a base or hearth a, and in the bottom of this chamber or fire-box, above the hearth, is a grate B.r The grate B consists of a series of circular hollow or tubular bars t b, having communication with each other at short intervals by hollow or tubular connections h b', and with the external air by means of air-inlet openings b.

The inner circular portion of the grate connects by a series of radial hollow arms b3 with a central hot-air chamber or drum C at its bottom. Secure to the upper or top edges of the fire-box or combustion-chamber and the drum C is the top plate A of the said combustion-chamber or nre-box. l

Encircling the combustion-chamber or firebox is a casing or cylinder D extending some distance above the fire-box, and between them is an air-space into which external air is admitted through openings ce, provided in said casing near its lower or bottom edge. Upon the outer vertical surface of the fire-box or combustion-chamber is secured a series of spiral ribs cl cl, dividing up the space between said chamber or fire-box and the casing D into a series of spiral passages, as shown.

In the upper part of the casing or cylinder D is the oven or cooking-chamber E, whose bottom E rests a short distance above the top of the combustion-chamber, providing a passage e.

The bottom E has in it a series of perforations h h and a central opening t', opened and closed by a valve or damper j. In the top F of the oven or cooking-chamber is a number of air-openings g g, opened and` closed by means of valves or dampers g g operated, either singly or in pairs, by rods g2, one secured to each valve, or to two valves, as shown, as may be desired. These rods are guided in cleats or guides secured to the top F, while the valves themselves are suitably retained imposition by means of flanges or cleats, also projecting from or secured to said top.

To the rear side of the casing or cylinder D is secured the stove-pipe collar 7c, having connection with the combustion-chamber, while also at a point farther up, opposite theV ovens, is a similar collar l to permit the taking, by means of a suitable pipe fitted thereon, of the hot air from the oven, and further utilizing it at a distant point-as, for instance, in heating an apartment or room.

To the upper end of the casing is supplied a number of hot-air-exit valved nozzles g3, to which may be also applied pipes for conducting the hot air to an upper story or room or rooms.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

l. In a combined cooking and heating stove, the tire-box having the spiral ribs on its outer surface Vdividing up the space between said box and the outer casing or cylinder, the cen` tral hot-air chamber in said fire-box, the airconducting grate, and the oven having the valves in its top and bottom, substantially as set forth.

2. In a combined cooking and heating stove, the fire-box or combustion-chamber having the spiral ribs on its outer surface dividing up the space between said box :1nd the outer casing or Cylinder, the central hot-air clump ber in said fire-box, the air-Conducting grate, the oven having the valves in its bottom and top, and the hot-air-exit valved nozzles applied to the top of said easing' 01I cylinder, substantially as set fort-l1.

In testimony whereof Inllx mysignnbul'e in presence of two witnesses.
